throughout history. Today, blood tests can be performed to determine if a person has developed an illness. From the data provided in the chart below, which person has been recently infected with a disease? Blood component counts Red Blood Cells White Blood Cells Platelets Jin 3000 350 120 Amar 3250 365 115 Nick 3100 800 115 Tara 3200 315 125 Nick a. b. Jin C. Amar

A person with the blood type B- would... O be missing the Rh factor (antigen D) on their red blood cells O have antibody B on their red blood cells O have both antigen B and antibody B O have antibody B in their blood plasma

. We commonly fight bacterial infections by developing a fever. Our body temperature may rise from a normal 37ºC to 41ºC or higher. It has been established that infections clear more quickly if accompanied by a fever. Why might this be true?

16. The Type A Transferase enzyme, attaches N-acetylgalactosamine (GalNAc) to H-antigen epitopes; the Type B Transferase enzyme instead transfers galactose (Gal) to the H-antigen. Individuals with Type A blood thus have at minimum one copy of the active Type A Transferase, those with Type B have at minimum one copy of the active Type B Transferase, those with Type AB have one active copy of each, those with Type O have neither. Imagine an AB individual who acquires a mutation in their Type B Transferase gene that allows it to be active with either Gal or GalNAc. Make sure to include a brief justification for your answer to each question below. a. What blood type antigens would this individual express? b. If this individual had a child with a normal O partner, what possible blood type antigens could the child express? c. If this individual had a child with a homozygous dominant B partner (BB), what possible blood type antigens could the child express?
